1812J2000682MJTE03

Overview

The Knowles Syfer 1812J2000682MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a C0G (NP0) dielectric material, ensuring stable capacitance over temperature and voltage variations. The component has a nominal capacitance of 6800 pF with a tolerance of ±20%. It is rated for a DC voltage of 200 V and operates within a temperature range of -55°C to +125°C. The physical dimensions conform to the standard 1812 (4532 metric) package size.

Feature Summary

• Utilizes C0G (NP0) dielectric for high stability and low loss
• Designed for high-reliability surface-mount applications
• Capable of operation in extreme temperature environments

Applications

• High-frequency circuit filtering
• Precision timing and oscillator circuits
• General-purpose decoupling in sensitive electronics

Procurement Notes

Verify the specific suffix 'JT' against official Knowles Syfer documentation to confirm termination type and packaging configuration. Ensure that the 1812J series designation aligns with the required reliability grade for the target application. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and any recent product change notifications affecting this part number.

Selection Notes

Select this component when a stable, non-ferroelectric capacitor is required for high-frequency or precision analog circuits. The C0G dielectric ensures minimal capacitance drift with temperature changes compared to X7R or Y5V types. Consider the 200V rating and 1812 footprint constraints during PCB layout. Validate that the ±20% tolerance meets the circuit design requirements for signal integrity.

Part Context

This part belongs to the Knowles Syfer 1812J series of general-type MLCCs. The series is characterized by its use of C0G dielectric materials, which are preferred for their linear behavior and high Q-factor. These capacitors are commonly used in RF, microwave, and other high-performance electronic systems where consistent electrical performance is critical under varying environmental conditions.
